    Perhaps make your own. e.g. from a springy wire spaced a small distance from a contact? Paper dropped on wire causes wire/contact closure and LED to light. You might want to add a monostable or latching circuit to keep the LED lit for a defined time.

    Or use a lever to amplify the force, and spring calibrated for the lightest weight you want up measure.

    What exactly are you trying to accomplish? Maybe there's a different and better approach.

    What's the lightest weight you want to detect, and how will the "scale" thing be physically put together?
